Question

what is the formula and d.f of gravitational constant?

Answer 1

According to Newton's law , given any two objects having mass m 1 and m 2 (inkilogram s) whose centers of mass are separated by a distance r (in meter s), there exists an attractive gravitational force F (in newton s) between the objects, such that:

F = Gm 1 m 2 / r 2

The value of G in this equation is approximately equal to 6.67 x 10 -11newton meters squared per kilogram squared (N x m 2 x kg -2 ). This constant is uniform throughout the Solar System, and apparently throughout our galaxy and other galaxies in its vicinity.
